研究了不同类型和厚度的环氧胶粘剂对三种异种钢板电阻焊中熔核形成的影响。采用改进的有限元模型对三板焊接温度分布进行了估计，并通过金相试验进行了验证。结果表明，在相同的焊接参数下，焊键的起焊时间和熔核尺寸均比电阻点焊早，且较大。与粘结剂Betamate Flex相比，粘结剂Terokal 5089在三片钢板的焊接接头中，由于钢板之间的界面带来的静接触电阻增加，焊缝熔核尺寸增加更大。然而，上述胶粘剂的粘结线厚度对三种不同钢板的焊接尺寸影响不大。
This study focused on the nugget formation in resistance welding of three dissimilar steel sheets influenced by different types and thicknesses of epoxy adhesive. An improved finite element model was employed to estimate the temperature distribution in three-sheet weld-bonding and was validated by the metallographic tests. Results showed that the weld initiation time and corresponding nugget size for weld-bonds would be earlier and larger than that of resistance spot welds in term of the same welding parameters. Compared to the adhesive Betamate Flex, the weld-bonding joint of three-sheets with adhesive Terokal 5089 would have a greater increment of the weld nugget sizes due to the increase of the static contact resistance brought by the interfaces between the steel sheets. However, the bond line thickness of the previously mentioned adhesive would take little effect on the weld sizes in weld-bonding of three dissimilar steel sheets.
